To a/ZZ' whom it may concern:

Be it known that I, IsrnoR KrrsEE, of the city and county of Philadelphia, State of Pennsylvania, have invented certain new and useful Im rovements in Telephony, of which the followmg is a specification. My invention relates to an improvement in the construction and installation of circuits for. telephonic transmission; and it consists,

substantially, in the novel arrangement herecompanyin drawings, and'pointed out in the appended c aims.

a diagrammatic view of a telephonie circuit embodyin my invention. Fig, 2 is a similar view in W ch the induction-condensers are provided with switches, the function of which will later on be described. Fig. 3 is a plan view in perspective of yone of the induction-condensers. Fig. 4 is a front view of. a section of a pole to which the inductioncondenser 'is attached.

A A are the 'main-line wires connected to,

two' telephoniel stations, provided with .the transmitter E, battery F, inductorium C, re- Ceiver. D, the design-ation of both of the stations being the same with the exception that vthe letters of the right-hand' station are provided withthe additional numeral 1.

v In series with the line-wire are connected the rimary artsof the induction-condenser G, the secon ary parts of which are connected to the derived circuit, consisting of the linewires Band. B Vand the receiver D2. The first derived circuits, loo ed ofi from the ywires A and A", are rovi ed with a'second induction-condenser with the aid of which a subderived circuit ishcarried from the irst .branch circuit."

In Fi 2 each part of each condenser is provide` with the switch g and each of the derived 'circuits is provided with a fullyequi ped telephonicstation. These stations are esignated by the same letters as the station in the'main line with the exception or' the additional numeral 2 to each .of the let-` ters. 4In 'Fi 3, in which the condenser is shown in detai the separate series of conductingleaves are desi ated, respectively, by the 'let- .ters Hand H or the primary part of the condenser and I and I for the secondary part of the condenser, each series of leaves being connected to one contact-point. the conducting-leaves designed 't0 form 'the Amary part. of the condenser.

As illustrated,

secondary part of the condenserare intervening' between the leaves forming In Fig. 4, J is a pole, Isuch as is usually employedv `to carry telephonie or telegraphlc wires, and -ata convenient height the condenser Gis secured by any of the well-known means.

I will know describe the modus ,operandi of my invention.

'If it is desired to use the main station alone and none of the Vderived stations, then the -switches ofthe primary parts of the con- Referring now to the drawings, Figure 1 is densers-placed in the main line are closed.

the pri- A vof Inthis position the main line forms a circuit of. its own, as does each of the derived circuits, it being understood that each of the derived circuits may have as many telephonie stations as are desired. But letus suppose that one oi theV subscribers at the main station wishes to communicate' with one of the subscribers at one of the'branch stations. It

is only necessary for the operator at the main station to telephone to the operator at the intervening main stationthe following message, f Give me clear way to (Naming the station.) *The Operator. has only to throw the switch of his condenser, and the .path will be open' for conversation to the branch circuit.

It'oiten happens, especially in newspaper- Work, that one station wishes to communicate with all the Istations'along its vroute or connected to this route by branchstations. In this case all switches of all stations are left open, and the transmitted speech will be heard byeveryone of the oi'ces or 4subscribers connected either with the main line or sublines. 4

, It is unnecessary to dwell on the simplicity and importance of ths'invention, aspersons versed in the art will readily understand the degree of iexibility attainable with the aid of this converting device in telephonie circuits. Y

IOO

For better understanding of the -device i such as described and illustrated I state here that said device is 'designed to perform and `does in actual practice perform the same function as the well-known induction-coil and consists, like such coil, of two elements, primary and secondary elements, the second- .A ary in inductive relationto the primary, each element rovided with twoiterminals, the terminals o the primary elements connected to one circuit, generally called the generating primary elements connected' to a primary or generating circuit and secondary elements connected to a circuit carrying the induced im ul'ses.

aving now described my invention, what I' claim a's'new, and' desire to secure hy Let- 1'. In a system of telephonie transmission, a' main line provided with one or more telephonicstations, one or more induction-condensers each consisting of primary and secondary parts, thepprimary parts being connected to said main line, and branch circuits forjgthe secondaryT parts of said condensers.

2. In a system oftel'eplienic transmission' consisting of. a main line provided withh one or more telephonic stations, one or more induction-condensers, connected' with their primary part or parts to the main line, and

with their secondary part or parts to an inde'- pendentline, said independent line provided with av telephonie receiver.

S'. .In a system of telephonictransmission, a series of' inductionecondensers, the primaries oiwhich are connected to the main line and the secondari'es of which' are connected to in'- dependent lines, the main lineas Well as the independent lines provided eacll with one or more telephonie stations.

4. Al telephonie-line consisting of the mainline wires having interposed therein in series, the primary part or parts of one or more induction-condensers, each of said inductioncondensers consisting of four series of conducting-leaves, insulated from each other, two series designed to form the primary and two series designed to form the secondary part of said condenser;

5. In a system of telephonie transmission, the combination of two' or more telephonie stations, a line-Wire connecting the'same, one or' more induction-condensers, the primariesof'which are connected inseries to saidline- Wires, and the secondaries of which' are connected to independent line-Wires, provided each with one or more telephonie stations.

6. A system of telephonie communication, consisting of'a series of telephonie stations connected together through a main line and' one or more derived'l lines, and;i11duction-c'ony densers electrically connecting the derived' lines with the main line.

7. In telephonie' communications, a* main line provided-with one or more telephonie stations, induction-condensers ,1 tlle'prlmarl'es of which are connected in series to'saidmain line, and means for'ea'cli of said condensers to open and shunt thesame'. i Y 8. A line for'electrie transmission', having! interposed therein' in' series th'eprimary of an' induetion-condanser, the secondary of Whicll is connected with a second and independent line', said condenser'provid'ed witli meansto openv and shunt the same.
